|Quantum Particles - NASA|
Particles of matter in classical physics can be considered as objects that have a definite location in space at any given time. However, in quantum theory, particles are given a probability of being located in a particular space at a particular time. In this animation, particles pop into and out of existence in varying spaces and at varying times. Note: In this animation, quantum particles pop into and out of existence in varying spaces and at varying times...

|Vela Pulsar in Gamma Rays - NASA/DOE/Fermi LAT Collaboration|
This movie shows pulsed gamma rays from the Vela pulsar as constructed from photons detected by Fermi's Large Area Telescope. The Vela pulsar, which spins 11 times a second, is the brightest persistent source of gamma rays in the sky. The movie includes data from August 4 to Sept. 15, 2008. The bluer color in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts (1 GeV)...
